COTTON-GIN.

Specification of Letters Patent.

Patented J une 5, 1917.

Application filed J une 19, 1916. Serial N o. 104,541.

To all whom t may concern:

Be it known that I, EDWARD L. HUNTS- MAN, a citizen of the United States, residing at Rochester, in the county of Haskell and State of Texas, have invented certain useful Improvements in Cotton-Gins, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in cotton gins, one object of the invention being the provision of an attachment for a gin feeder to separate cotton from the burs during the gin operation, the same being especially adapted for use upon. cotton containing an excess amount of bolls.

A further object of the present invention is the provision of an air suction device whereby the cotton will be removed from the burs before its entrance into the gin instead of carrying to the huller breast the cotton and burs together.

A still further object of this invention is the provision of a simple and comparatively inexpensive mechanism which is adapted to dispense with the cotton sliding board used in cleaner feeders for cotton and which will operate to separate the cotton from the burs or bolls'before the entrance thereof upon the gin stand or huller breast. y

In the accompanying drawings Figure 1 is a side elevation of a cleaner feeder with the present attachment in use,

such attachment being shown in section to illustrate the various positions of the parts.

Fig. 2 is a top plan view thereof.

F ig. 3 is a view on an enlarged scale of the present attachment showing by arrows and spears the directions of travel of the cotton and burs.

Figsa and 5 are detailed views of various parts.

Referring to the drawings, the numeral 10 designates the cleaner feeder mechanism which is of any preferred form, the present separating attachment 11A being introduced in lieu of the usual cotton sliding board applied in connection with a cleaner feeder.

This attachment consists of a casing 12 which has mounted therein a slanting partition 12 for dividing the casing into an upper compartment and a lower compara ment in the latter of which is mounted for the pipe also passes through the ribs and draws the cotton so that it will adhere to the cylinder 13 to be pulled olf the saw by the suction and to lodge against the perforated plate 18.

The roller 19 is substantially six inches in diameter and is provided with the elastic or rubber belt fiaps 20 which serve to direct the action of the suction to the top of the cylinder and which clean the cotton from the perforated plate and direct it down the lower compartment which is arranged in communication with the top of the cotton roll chamber 21 of the gin stand 22.

An arcuate shield 21 extends from the partition 14 and is positioned beneath the cylinder l'terminating short of the roller 1,9 so as to prevent the action of the suction of air on the under surface of the cylinder.

A slatted belt 23 which is the exact width of the feeder is provided with a plurality of short spikes or pins 24 to receive and rake the burs from the ribs and cause them to move down partition 12 into the huller breast 25 of the gin stand with which the upper compartment is arranged in communication, the upper end of the upper compartment being incidentally arranged in communication with the outlet of the feeder 10.

It will thus be seen that with this attachment the cotton will be completely separated from the burs as it passes through the regular gin stand feeder to the in stand and that the cotton thus cleaned will be fed direct into the cotton roll so that the burs are separated and aredisposed of in the same manner as with the regular double breast gin stand.

With this attachment by the aid of the suction all small locks of cotton are saved and ginned and by separating the larger percentage of the cotton liber from the burs at this operation, the operator can maintain a full rollof cotton in the stand and save a greater percentage yof the lint and seed.

What I claim as new is 1. rlhe combination with ay gin stand feeder and a gin stand, of a casing positioned between the feeder and the stand and having two compartments therein one of which is arranged, in communication with Y the outletfof the feeder and with the huller breast of the gin stand while the other compartment is arranged in communicationw with the first compartment and with the top of the cotton roll chamberof the gin stand, and coperative means arranged in the compartments for separating the cotton Lfrom the burs so that the separated burs and cotton will be respectively delivered to the huller breast and the cotton roll chamber of the gin stand.

2. The combination with a gin stand feeder and a gin stand, of a separating attachment disposed between the feeder and the stand including a casing having two compartments therein, one of which is ar ranged in communication with the huller breast of the gin stand whilefthe other is arranged ink communication with the cotton roll chamber of the gin stand, a saw cylinder rotatably mounted in one compartment of the casing, a suction device connected to one` end of the casing the suction of which removes the cotton from the cylinder, a per-V forated plate arranged in front of the suction device forpreventing the passage of cotton 't therethrough, coperative means mounted in the casing and interposed between the plate andthe cylinder for directing the action of the suction to the top of the cylinder and for removing cotton from the plate and directing it to the cotton y,roll chamber of the gin stand feeder, and an endless-conveyer for cooperating with the 'saw kcylinder for carrying burs away from the cylinder and directing them into the huller breast of the gin stand. y A f 3. rllhe combination with a gin stand feeder and a gin stand, of a casing arranged between the feeder and the stand and provided with two compartments one of which communicates with the huller breast of the gink stand while the other communicates with the cotton roll chamber of ythe gin stand, anendless conveycr mounted in the top compartment of the chamber for directing burs into the huller breast of they gin stand, a saw toothed cylinder rotatablyr mounted in the other of the compartmentsv of the casing for engaging and separating cotton from the burs, a pipe extending from one end of the casing and 'through which there is a suction action for removing cotton from the cylinder, a perforated plate arranged in front of the pipe" for kpreventing the passage of cotton therethrough, a shield mounted in the casing beneathy the cylinder' for preventing a suction action on the under surface of the cylinder, a cooperating roller arranged between the plate and the cylinder for directing the suction action to the top of the cylinder and for -removing cotton from the perforated plate and directing it into the cotton roll chamber of the gin stand.

4. The combination with a gin stand cleaner feeder and a gin stand, of a casing arranged therebetween, a partition providingy two compartments in the casing the upper of which communicates with the cleaner feeder'rand the huller breast of the gin stand while the lower compartment communicates with the cotton roll chamber of the gin stand, the partition being provided with an opening for establishing communication between the two compartments, ribs arranged across the opening, a saw toothed cylinder rotatably mounted in the lower compartment of the casing and having the teeth thereof yprojecting between the ribs into the upper compartment for engaging cotton which passes down the partition, a pipe extending from one end of the casing and through which there is a suction action for removing cotton from the cylinder, an arcuate shield extending through the partition and arranged beneath the toothed cylinton: into the cotton roll chamber of the gin stand, and conveying ymeans mounted 1n the upper compartment ofthe casmg for 'cooperating with thesaw toothed cylinder and for carrying burs down the partition .so

that they vmay be deposited in the huller breast of the gin stand. Y

5. The combination with a cleaner feeder and a gin stand, of an attachment arranged therebetween including a casing, a partition providing two compartments in the casing the upper of which communicates with the feeder and with the huller breast of the gin stand while the lower compartment communicates with the cotton roll chamber of the gin stand, the partition being also provided with an opening establishing com` munication between the two compartments, ribs arranged across the opening, a toothed cylinder rotatably mountedV in the lower compartment of the casing and having the teeth thereof projecting between the ribs into the upper compartment for separating cotton from the burs, a pipe extending from the casing and through which there is a suction action, a perforated plate arranged in front of the pipe for preventing thepassage of cottonthroughthe pipe, an arcuate shield connected to the partition and arranged between the toothed cylinder for preventing a suction action on the under surface of the cylinder,` a roller rotatably mounted in the casing between the plate and the toothed other compartment of the casing for copercylinder, a plurality of flexible flaps arating with the saw toothed cylinder for 1 0 ranged on the periphery of the roller for moving burs away from the cylinder So that directing the action of the suction on the they may be 'fed into the huller breast of the top of the cylinder and for removing cleaned gin stand.

cotton from the plate and directing it into In testimony whereof I aliiX my signature. the cotton roll chamber of the gin stand,
